I began working on the Step Installation section by first drilling the four holes in the Step Support Blocks (F-1038) per the dimensions given. I deburred the edges of the Steps (WD-1007) and inserted them into the Step Mounting Brackets (WD-1008). I slipped the Support Blocks (F-1038) over the end of the tubes and then positioned them against the web of the Mid Baggage Ribs (F-1020). I adjusted the position of the Support Blocks per the instructions and then match-drilled #12 two of the pre-drilled holes into the Mid Baggage Ribs (F-1020). I then temporally bolted those holes to the Mid Baggage Ribs, removed the Steps, and match-drill #12 the remaining holes. Next I marked the top, aft, and outboard face of the Support Blocks before I removed them and the Steps from the Mid Baggage Ribs. After deburring the holes in the Mid Baggage Ribs, I bolted the Support Blocks back onto the Mid Baggage Ribs and reinserted the Steps. Now I could began adjusting the position of the Steps by using the 45.25 inches to set the proper sweep angle of both Steps. Once I got the sweep angle set on the Steps, I used the guide hole to match-drill #30 through the Steps and the Step Mounting Brackets. I removed the Steps and deburred the holes before I began installing the Step Support Bushings I bought from TCW. I then reinstalled the Step and the bolt before I clecoed the Baggage Floor (F-1022A) to the fuselage. This way I was able to locate where I will need to install inspection panels in the Baggage Floors so that I will have access to the Step bolt in the future, if needed.
